LID FOR STOVES.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed July 23, 1913. Serial No. 780,753.

. To all whom itmay concern:

Be it known that I, EDWARD DAUM, a citi zen of the United States,residing at Okaton, in the county of Lyman and State of South Dakota,have invented new and useful Improvements in Lids for Stoves, of whichthe This invention relates to lids for stoves of various kinds and,especially for cooklng The invention has for its object to produce a lidhaving passages for the circulation of air which during its passagebecomes heated and is discharged upon the fire, thereby promotingcombustion to such an extent that a large proportion of the productsusually escaping in the form of smoke will be consumed and acorresponding amount of fuel saved.

A further object of the invention is to' which will be hereinafter fullydescribed andparticularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,

but that changes, alteration and modifications within the scope of thedevice as claimed may be resorted to when desired.

In the drawings, Figure 1 is a top plan view of a lid constructedaccording to the invention. Fig. 2 is a side elevation of the same. Fig.3 is a top plan view with the top or cover plate detached. Fig. 4: is abottom plan view, partly in section, with the bottom plate detached.Fig. 5 is a sectional View taken on the line 5-5 in Fig. 3.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The improved lid in its preferred construction, as here illustrated, iscomposed of three principal parts or members, namely, a top or coverplate A, a bottom plate B and an intermediate body member C. The bodymember C is composed of a cylindrical rim or annulus 15 having aboutmidway between its upper and lower ends a diaphragm 16, on

the upper side of which a plurality of substantially L-shaped channels17 are formed, the walls of said channels being composed in part offlanges 18 rising from the diaphragm and radiating from a centralannular flange 14, and partly of portions of the rim 15.

The L.shaped channels may be described as being disposed incircumferential series, and two of saidchannels which are specificallydesignated by 17 a and 17 may be regarded and will be described as beingthe first'and the last of the series. The first channel l7 communicatesat its inner end, that is to say,

near the center ofthelid, with an intake opening 19 formed in the topplate A, and into said opening is threaded anintakepipe '20 which iscurved to form an upwardly extending arched portion 21 and a straightportion 22, the latter lying flat on the surface of the top member A andhaving its end cut ofii obliquely, as seen at 23, for the readyadmission of air, while the arched portion 21 will prevent any liquidthat may boil over from pots or kettles from entering through the intakepipe. lhe outer terminal of each channel communicates through an opening24: lying adjacent to the rim 15 with one of a series of compartments 25formed on the underside of the diaphragm by flanges 26 radiating fro-m acentral annular flange 27. Each compartment 25 communicates through anopening 26 with the inner end of the next channel 17 of the series. Thelast channel of the series, 17", is provided with a return flange 27that communicates at its inner end through a special opening 28 with thelast compartment of the series which is specially designated as 25", andthe portion of the rim 15 which constitutes the outer wall of saidcompartment 25 is provided with apertures 29 for the escape of heated amThe top plate A, the bottom plate B and the intermediate body member Care assembled together by means of bolts 30 for the passage of whichsuitable apertures are provided, and it will be seen that when the partsare thus assembled, the bottom plate aflords a closure for the lowerends of the compartments 25, 25", while the top plate A constitutes aclosure for. the upper ends of the channels 17, 17 and 17 The top plateIn the operation of this device, ,t'hQflIIl proved lid is placed on thestove or range :above the fire. .Airentering through the intake pipe 20will circulate through the channels and through chambers or compartmentsprovided for the purpose above and below the diaphragm 16, and in --t-he"respective compartments '25 the air will be permitted to expandand'will be subjected to "the-intense heat from the ifire. 27 of thelast channel 517* ofthe series, the

Fromthe "branch heated air will {be --discharged into the lastcompartment 25 -;near the inner end of the latter, and the air "afterpass11ng 'thro-ugh' said compartment -will escape through ;-the

apertures29 andbe discharged--upon-'-the fire with the effect-0 fpromoting combustion --to a very "appreciable extent. The constructionof :the improved device is very simple andiinexpensive, it beingcomposed :o'f three simple castings-assembledtogetherby means ofordinary stove bolts. It obviously be made of different SlZBSfiOifil'."the holes '-of --stoves"and--ranges o f various dimensions.

vHaving thus described the invention, what is claimed as .new, 1s

1. An air heating and circulating fuel' saving stove lid, thesameincluding 'a top ,plate having an intake opening and a pipethr'eadedzinto said opening, said pipe being provided with an upwardlycurvedarched portion to exclude liquids from the intake opening.

2..An air heating and circulating fuel 'savingstove lid havingaircirculating channels and chambers, said lid including a top plate havinga vertical intake opening, a

circumferential rim having exit openings, and a'n-inta-ke pipe threadedintothe'intake opening, said pipe having an upwardly curved arch portionto exclude liquids from "the'inta-ke opening,-and a horizontallydisposed portion resting on the top plate, said horizontally disposedportion being cut off obliquely at 1 its outer end.

Intestimony whereof I ai'fix my signature in presence of two witnesses.
